Creating special Access Token Links

I need to pull various third party Instagram applications' access tokens. I want obtain their access tokens they have for users that give permission to that application. This access token is found in the webpage source code when you are on the "Manage Applications" page of the instagram profile Each application using instagram creates an access token for each user that uses that 3rd party app. I need a better way to get hold of the access token instead of looking at the webpage source code. It is a very manual tedious task that I want to automate. So for example, if i go to my instagram account right now and get access token, I need to go to "Manage Applications" on my profile on my computer, then open the source code page, and then find the access tokens all my third party apps use. I want to automate it for any user that wants to know their accounts access tokens. I have a instagram promoting website. and what I want to do on the website is this: have users login 5 third party apps through my website, then all the access tokens for that user will be transferred onto a database which I can use to help them grow their instagram.
